I have replaced the thermostat and the heater core and still have problems. Some times it is just mild warm and sometimes no heat at all. How much does a back flush cost?
Do you
have the same problem?
Yes
No

Are the heater hoses hot when up to temperature? Are there any coolant leaks? Heater core could be restricted or there could be a problem with a blend door not operating correctly.
